AUTO IBUMPE'R.

Original No. 1,483,913, dated February 19, 1924, Serial No. 658,852, filed August 23, 1923. Application for reissue filed J'anuary 2, 1925. Serial No. 1,019.

of the charaoter stated that is strong in construction,so as to be adapted to withstand shocks and. impacts incident to its use, and. which may be constructed of few parts, not liable to become out of working order, and adapted to have quick, direct, and positive action when in use.

W1th the above and other objects in view, hereinafter stated, the invention consists of the novel construction, combination,and arrangement of parts hereinafter more specifically stated, and illustrated in theaccompanying drawings, wherein is shown a device emboding the structure of the invention in its preferred form, but it is tobe understood that changes,- variations, and

modifications ma be resorted to without de arting from t e scope of the invention. n describing the invention in detail, reference is part of this indicate corresponding parts throughout the several views, and where1n: Fig. 1 is a plan view of a device cmbodying the invention, mounted upon the axle bumper fram e on the bradt constructed of an automobile; and H Fig. 2 is a side elevation, partly insection and partly -Icr0ken away, taken on the line 22 of Fig. 1. the drawings, 1 repusual carrying wheels. A frame supporting bracket has its central portion 3 secured to the axle, preferably the underside there- Arms central portion of the bracket and are provided on their ends with sleeves 6, the inner surfaces of which fcrm b arings for longihad to the accompanymg r and full 'connected together at their -rear end by means of a cross bar 8, and attheir forward end by acrossbar9, preferably flattened incross section. A bumper frame or head 10 is secured t0 thefront cross bar of the frame in any suitable manner, such as by means of toits 11 which connect the inturned ends of the bumper head with the side bars 7. Yokes 12, extending in a plane at right angles to that of the bumper frame ma if demred, be Connected with the front an back portion of the bumper head.

Springs 13 are connected at one end with the axle, and at their other end with the rear cross bar 8 of the bumperfiame. These sprin s normally hold the bumper in a projecte position.

When the front bar 10 or -head of the bumper, strikes a person or obstacle in the path of travel of the machine, the-bumper rame, comprising the side bars 7, rear bar 8, and front bar .9, is moved backwardly through the. sleeves 6, thereby expanding the springs and cushioning the impact eXerted on the bumper. r

Upon therelease of the pressure against the front bar or frame of the bumper, the

springs 13 retract and return the frame of the bumper -to its normal position relative to the axle 1.

From, the foregoing description considered in connection with the accompanying drawings, the construction, mode of operation, manner of use, and the several advantages of the present invention will be clearly understood.

It Wi lbe seen that by mounting the as shown anddescribed, the side bars of the frame are each supported on two bearings ample bearings of said sleeves also prevent any lateral or tortional movement of the bumper frame.

The sleeves of the bracket, moreover, may

be of any desired length, so as to provide an extensive bearing for the bumper frame. By means of such construction the thrust exerted on the frame, When the bum r with an obstacle in its path, is taln of the machine from any strain or stresses resulting from the action-ofthe humper.

It will be also seen that because of the few parts necessary to form the dcvice, such" parts may be made at a minimum cost, and strcmg enough-to withstand any strains -to which the bumper may be subjected';

Instead of providing the bumper trame With a rcarcross bar, the side bars of the framemay be each provided with a cross head or bar and tension springs may be con nected With said cross head and with arms or studs connected with 't-he bearing sleeve, so that when pressure is applied to the head of the;bumper a brckward movement of the side bars Wi1l expand said springs, and the removal ofsaid pressure Will cause the springs-to. contract and press the side bars and*buffer head forward to its initial position.

What I claim as new and desire to secure by Letters Patent is 1. An auto bumper, comprising a support, a bracket mounted upon said Support and provided With inclined armshaving bearing sleeves at the outer ends thereof, a frame having side bars slidingiy mounted in said sleeves, a rear cross bar, a bumper head con nectcd with the forward end of said trame,

3. In an auto bumper, the combination with a support, a hracket' securcd to said support, and provided with inclined ztrms hav ing sleeves formed therewith, a bumper frame comprising side bars slidingly mounted in said sleeves above said support, a rear cross bar, a front cross bar, a bum-per head secured to the frdntcross bar, and springs connecting said support with said rear cross bar, and adapted to normally hold said bumper head in projected position.

4. An auto'humper, comprising a support, a bracket secured to the lower portion of s'aid support, and provided with 'sleevs spaced on opposite sides of said support, and having their axial lino extending above the horizontal plane of said support, a trame having side bars slidingiy monnted in said sleeves,a front cross bar, and a rear cross bar connecting thesides of said trame, and

SprihgS "connecting said support and sa;id

rear cross bar, and adapted to ndimally hold said bumper head in projectedposition.

5. An auto bumper comprising a support carrying boa-ring sleeves, a frame having side members, tension springs connecting the"inner end of said frarne with the support, the side memhers of the support extending through the 'bearing' sleevS Carried by'the support With the outer ends of said side members cxtending freely outward from the support and normaliheid inthe outermost position by said tension springs, and a bumper connected with the said outer ends of the frame.

6. An auto bumper, in combination with an ax1e, a bracket mOunted' upon Said ax1e and provided With inclined arms having bearing s1ecvcs at the outer ends' thereQf, a frame having' side bars slidingly mounted in said sleeves, a rear cross bar, a bumper hed connected with the forWard and of said frame, and springs connected With the rear cross bar ofsaid frame,and saidaide.
